IMPROVEMENT IN ANTI-FRICTION JOURNAL OR AXLE BEARINGS.

Specification forming part of Letters Patent No. 184,242, datedNovember14, 1876 application filed October 24, 1876.

To all whom it may concern:

Be it known that I, WARREN H. HAYNES, of North Sudbury, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Anti'Friction Journal or Axle Bearings; and I dohereby declare that the following is a full, clear, and exactdescription thereof,- which will enable others skilled in the art towhich it appertains to make and use the same, reference being bad to theaccompanying drawings, and t0.letters of reference marked thereon, whichform a part ofthis specification.

Figure l is an end view of a series of rollers in a journal-box, held bystay-rods inserted double through the rollers. Fig. 2 is a sectionalview of two rollers on line a; a; of Fig. 1. Fig. 3 shows rollers havingpivotal bearings in rings, held by stays inserted through the rings,sides of the rollers. Fig. 4 is a plan view of the rollers shown in Fig.3. Fig. 5 shows rollers held by the stay-rods inserted through elongatedplates instead of rings. Fig. 6 shows the same plates with the stay-rodsinserted double, one-half from each end of the rollers. Fig. 7 is atransverse section of one of the rollers, with the flattened sides oftwo stay-rods inserted through the roller. Fig. 8 is a detached view ofone of the double stays.

My invention relates to anti-friction bearingshaving anti-frictionrollers. The devices employed heretofore in such bearings for holdingthe rollers allow them to be moved out of their true line, causing themto bind against their bearings and increasing the friction. The objectof my invention is to prevent that binding and increased friction,

which [accomplish by means of double stayrods, which securely hold therollers in their true position, and ing twisted in the journal-box, ashereinafter fully described.

A is a journal-box, provided with flanges a, forming the way traversedby the anti-friction rollers. B represents a series of rollers,

I held in position by stay-rods, bent so as to form the middle brace 12and parallel sides b b, as shown in the drawings.

and extended by the,

prevent them from becom- These stays may be applied and fastened inseveral different ways. Figs. 1, 2, 6, and 7 show one side of the twoadjoining stays extended through the same roller, having a hole of theproper size through its center; and when the stays are thus applied thesides I) are flattened, so that the flat sides of the rods, wheninserted in the roller, lit together, forming one round spindle or axlefor the roller to revolve upon, as shown in Fig. 7 of the drawings.

In Figs. 3 and at the stays are shown in serted through rings 0. andextended by the sides of the rollers, which have pivotal bearings on theinner sides of the rings.

' in Figs. 5 and 6 the stays are inserted through holes in the ends ofelongated plates D, which are used instead of rings for connecting andfastening the stay-rods, and assisting to hold in place the rollers.

The plates and rings are dispensed with when the stays are applied andfastened, as shown in Figs. 1 and 2. The stay-rods may all be insertedat the same end of the rollers; or a part of them may be'inserted at oneend, and the balance at the other, and the ends of the rods may befastened by riveting or by bending over the ends, as shown in thedrawings.

It is readily seen that these double stays b b, connected by the middlebrace 12, formed of one continuous rod, must have more strength thanseparate or singlestays, to resist pressure tending to twist the rollersout of their true line in the journal-box.

What-I claim as new, and desire to secure by Letters Patent, is-

In combination with a series of anti-friction rollers, B, the doublestays b I), connected by the middle brace b, formed of one continuousrod, and applied and fastened substantially as and for the purposesdescribed.

In testimony that I. claim the foregoing as my own invention 1 affix mysignature in pres ence of two witnesses.
